Known as the Teewave AR.1 ? or the Gordon Murray T.32, depending on who you ask ? the roadster reportedly weighs in at less than 850 kilograms.

That?s about the same as a Lotus Elise, despite the car packing 240kg of batteries ? and, as Murray is keen to point out, more than 400kg less than the competing Tesla Roadster.

The lightweight, all-electric two-door may flaunt a sporty design, but its mid-mounted Mitsubishi i-MiEV-sourced electric motor only produces 47kW of power and 180Nm of torque. As such, the measure-of-all-sports-cars 0-100km/h time is a miserable 11.4 seconds ? as much as four seconds slower than some small-engined city cars ? and its top speed is an EV-typical 146km/h.

Despite its far-from-sporty performance, GMD says that combining efficient, environmentally-friendly engines and lightweight technology is the best weight to ?achieve power-to-weight targets?.

The batteries have a claimed range of 186km, and can be fully charged in about six hours.

The car took just nine months from concept to development.

Gordon Murray is also working hard to sell-on his T.27 city car which is reportedly being considered by three manufacturers.
